We tow a TJ wrangler. Small but light, and will go anywhere, even some places where walking is not an option.
The newer JK's are heavier, and JK 4 doors weigh as much as a full sized pickup!
Wife has a '010 liberty, it is towable. I just got an 03 Dakota AWD, it is towable as well.
The motorhome magazine guide is great, but is it current year vehicles only? How do you get back issues?
when in doubt, check the owners manual, though in some cases lately even those have been less than accurate. I believe the Chevy Cruze and many Escapes were originally rated to tow, but no longer are.
